The Arno XI is a hydroplane inspired by Achille Castoldi in the early 1950s and built by Timossi Azzano’s Cantieri boatyard located on Lake Como. Castoldi wanted to establish a world water speed record so he persuaded then Ferrari racing drivers Alberto Ascari and Luigi Villoresi to influence Enzo Ferrari to supply him with a 4.5-litre, V12 Ferrari engine; the same engine that gave Ferrari his first Grand Prix victory with the Ferrari 375 F1 at Silverstone Circuit in 1951. Castoldi managed to increase horse power by attaching two superchargers. The result was a 502 bhp speedboat, which he used to hit a 150.19 mph top speed in October 1953 on Lake Iseo. That remains the world speed record for an 800 kg boat till today 85cm long model boat- Fully Executed by hand with noble materials such as wood and mahogany and real leather for seats.
